RESILIENT TIRE.

Specification of Letters Patent.

Application filed August 2, 1910.

Patented Oct. 18, 1910.

Serial No. 575,118.

To all whom it may concern:

Be it known that I, DAVID A. YORK, citizen of the United States,residing at Northgrove, in the county of Miami and State of Indiana,have invented new and useful Improvements in Resilient Tires, of whichthe following is a specification.

My invention pertains to resilient tires such as are designed moreparticularly for use upon automobile wheels; and it has for its generalobject to provide a simple and durable tire including a coiled metallicspring, and possessed of great resiliency, and adapted to beexpeditiously and easily repaired when occasion demands.

My invention will be best understood by reference to the followingdescription when taken in connection with the accompanying illustrationof one specific embodiment thereof, while its scope will be particularlyclaimed.

In the drawings: Figure 1 is a side elevation, partly in verticalsection, of a portion of an automobile wheel equipped with my noveltire. Fig. 2 is a transverse section taken through the wheel felly andtire. Fig. 3 is a detail transverse section taken in the plane indicatedby the line 33 of Fig. 1, and showing the arrangement of one of theconnecting bolts relative to the telly and the spri.ug-holder.

Similar letters designate corresponding parts in all views of thedrawings, referring to which:

A is the felly of a wheel, which, in accordance with my invention, isprovided at suitable intervals in its periphery with transverse groovesa.

I 13 are circular, cover-retaining plates, disposed at opposite sides'ofthe felly A and having inturned flanges b at their outer edges.

0 is the circular spring-holder of my improved construction.

D is the cov'er of rubber or other suitable material, which is providedat its edges with outwardly directed flanges c, and E E are transversebolts through the medium of which the side plates B are detachablyconnected with the felly A and the springholder C, and the saidspring-holder C is effectually held against creeping around upon thefelly A.

As will be observed by reference to Fig. 3, the side of thespring-holder C that is opposed to the felly A is provided at inter-'vals with transverse grooves d, which grooves (Z are registered withthe grooves a in felly A to receive the bolts E, whereby said bolts Eare enabled to preclude the mentioned creeping of the spring-holder O,and in that way contribute to the strength and durability of the tire asa whole. The spring seat 6 in the holder 0 describes more than half of acircle, as shown in Fig. 2, and hence is enabled to prevent outwardmovement or material lateral deflection of the continuous coiled springF hereinafter described. It will also be observed that the side walls fof the circular spring-holder C are disposed at right-angles to theinner side of the said holder, and that therefore the said side walls fare calculated to support the sides of the cover D, and prevent theimposition of strain on the said cover when a lateral pressure or blowis imposed on the cover.

The spring F is a continuous coiled spring of metal, which is disposedin and held by the seat 0 of the holder C and has its ends connectedtogether in any suitable manner. By reason of the said spring F beingdisposed in the seat 6 that describes more than half of a circle, thespring is securely retained without diminishing in appreciable degreethe resiliency or cushioning capacity thereof, and from this it followsthat the cover I) is not required to hold the spring and is notsubjected to any pressure by the spring, but on the other hand theoffice of the said cover is to exclude dust and dirt from the spring,and at the same time con tribute to the resiliency or cushioningcapacity of the tire as a whole. In the inner side of its tread portionthe cover D is provided with a longitudinal chamber G which extendsentirely around the spring F, and is best illustrated in Fig. 2.

IVith a view to effectually preventing wear or deterioration of thecover D by the spring F, I surround the spring with a circular layer Hof fibrous material, and I further surround the said layer H with alayer I of raw hide. These layers extend between the opposite sides ofthe cover D and abut at their edges against said sides with the resultthat they are enabled to effectually prevent the infliction of anyinjury by the spring on the cover. It will also be noted that therawhide layer I is arranged against and reinforces the tread portion ofthe cover D, and that the chamber Gr in said tread por-,

tion serves the two-fold purpose of rendering the tread portion light inweight and increasing the resiliency of the tire as a whole.

\Vhen it is necessary for any reason to gain access to the interior ofthe tire, the bolts E and the side plates B may be removed, and then thecover D can be readily taken ott' to expose the spring F and the partsadjacent thereto.

It will also be gathered from the foregoing that it is practical toconstruct both the telly A and the spring-holder C of wood or othermaterial that is light in weight, though I would have it distinctlyunderstood that the said felly and spring-holder may be constructed ofany other material or materials without affecting my invention.

\Vhile I have shown and described one form of my invention, it is to beunderstood that I am not limited to the details or the form or relativearrangement of parts disclosed, but that modifications may be madetherein without departing from the spirit thereof.

Having described my invention what I claim and desire to secure byLettersPatent,

In a resilient tire, the combination of a wheel telly having transversegrooves at intervals in its periphery, a circular holder, of less widththan the felly, snugly surrounding the Vertical-central portion of thetelly and having straight sides extending from its inner side to itsperiphery and also having a seat in its periphery and further havingtransverse grooves in its inner side regis tered with those of thetelly, cushioning means arranged in the seat of said holder, a coverhaving side portions arranged at opposite sides of and braced by theholder and also having edge portions bearing against the periphery ofthe telly, at opposite sides of the holder, cover-retaining platesarranged at opposite sides of the telly and having means for cooperatingwith the edge portions of the cover to confine said edge portionsagainst the telly and the holder, and transverse connecting boltsextending through the said plates and occupying the registered groovesin the telly and holder.

In testimony whereof I have hereunto set -my hand in presence of twosubscribing witnesses.
